At some point in your HR career, you’ll run into a trainwreck of an employee with problems that just seem to escalate. It may start with a small injury and a workers’ comp claim. That can turn into a dispute over alleged harassment and retaliation. Eventually, she may even claim she has developed deep psychological scars … If she says she can’t work and has a doctor who supports her, you may be able to use the medical assessment to your benefit.
